Sir John Hubert Worthington RA (4 July 1886 – 26 July 1963) was an English architect.
Worthington was born at Chorley, Alderley Edge, the youngest son of the architect Thomas Worthington. He was educated at Sedbergh School from 1900–1905 and then at the Manchester University school of architecture, before being articled to his half-brother Percy. From 1912 until the outbreak of the First World War, Worthington spent two years working with Edwin Lutyens, whom Worthington found to be inspirational.
Worthington fought with distinction as a captain in the Manchester Regiment, and was severely wounded on 1 July 1916 during the offensive on the Somme, but he survived overnight in a shell hole and was rescued the following day. He rejoined Percy in the family firm in 1919.
In 1929, Worthington was appointed Slade Lecturer in architecture at Oxford University, and later designed many buildings for the University and its colleges, as well as the internal restoration of the Radcliffe Camera in 1939 and the Bodleian Library in 1955. Following Percy Worthington's death in 1939, Hubert became the principal of the firm. In 1943, Worthington was appointed by the Imperial War Graves Commission (now, the Commonwealth War Graves Commission) as principal architect for Egypt and north Africa, work that involved the selection of sites and the design and supervision of the various cemeteries and memorials to the fallen and missing; among them one at Valletta, Malta, to missing airmen. The cemetery at El Alamein, which contains more than 7,000 graves, was designed by Worthington; as was the Heliopolis War Cemetery. His major post-war rebuilding commission was the Inns of Court, London, work carried out jointly with Sir Edward Maufe and T. W. Sutcliffe. Of more personal interest to Worthington was his work on repairing the damage caused to Manchester Cathedral during the Manchester Blitz of 1940, a task that was not completed until 1955.
